JOSEPH PIERINGER, OF JERSEY CITY, NEW JERSEY, ASSIGNOR TO WESTERN ELECTRIC COMPANY, OF CHICAGO, ILLINOIS, A COR- YPORATIO'N OF ILLINOIS.

HEAD TELEPHONE SET.

To all whom it may concern:

Be it known that I, JOSEPH PIERINGER, a citizen of .the United States, residing at Jersey ,City, in the county of Hudson and State of New Jersey, have invented a certain new and useful Improvement in Head Telephone Sets, of which the following is a full, clear, concise, and exact description.

My invention relates to a head telephone set, and'has' for its object an arrangement of the transmitter and receiver. on a harness adapted to fit over the head of the user in such manner that the Weight of the transmitter and receiver will balance each other and the various parts will be conveniently assembled for use.

My'invention is especially adapted for use on man-of-war vessels, in which case it is necessary or at least desirable to have the re ceiver held constantly to the ear of the user. In my invention the transmitter and receiver are supported by a head-harness in such positions that the receiver is held over one ear and the transmitter over the other, thus producing an almost perfect balance of weight. The mouthpiece is adjustably mounted with reference to the transmitter. Ear-caps may be secured to both the receiver and trans mitter, thus providing for the comfort of the user, as Well as excluding outside noises.

Means are also providedfor securely'holding the apparatus 111 proper position.

My invention may be readily understood from the accompanying drawings, in which-- Figure 1 is afront elevation of the apparatus-constituting my invention. Fig. 2 is a detail view. of the transmitter. Fig. 3 is a section on the line 3 3 of Fig. 2.

The harness preferably consists of two straps AMA, adapted-to fit overthe top and band A serving to hold said straps properly spaced apart. The ends of the straps A A are connected to each other by rivets a. The harness is made adjustable in size by buckles,

as shown in the drawings.

The transmitter B and the receiver 0 have each a lug b extending from its shell or casing.

opening is provided ineach lug for the reception of a rivet a, by which means the two instruments are secured to the harness on op-.

posite sides thereof. Bindingiposts, to which are attached,

are placed within the shells of the transmitter and receiver in the usual manner. Ear-caps E E, preferably of soft rubber, extend from each instrument and are adapted to completely surround the ears of the user, so as to exclude outside'noises and also to prevent said instruments from uncomfortably bearing against the head of the user. These ear-caps may be secured to the two instruments in any suitable way.

I have shown means for attaching t e ca to the transmitter, in which an annular p ate 7c, secured by inFi s; 2 and 3 a convenient screws to the base of the transmitter, serves" 1too clamp the cap E between said plate and ase.

A slip-block F passes over cordsD and D, by which means the cords may be drawn close under the chin. The cords -D D are made stiff by a metallic winding d or in anyother suitable manner, so that when the cords are drawn under the chin the instruments are pressed directly toward the ears and the throat is left free. tage, since a cord not so stiffened would when drawn under the chin bear against the throat in such manner as to be uncomfort- This is a distinct advanable to the user and would also interfere with his articulation.

The mouthpiece M of the transmitter is made adjustable with reference to the shell or casing, so as to be readily placed in any desired position by the user. This is most clearly shown in Fig. 3. The inner wall of the casing of the transmitter has an opening throu h an elbow G provided with a screwthrea ed outlet g. Threaded in this outlet is a hollow tube 1-1, which extends through the ear-cap E and has a spherical head h, whereby a ball-and-socket connection is provided between the tube H and a tube I. A washer 'i' fits over the end of the head h, and one end of a coiled spring 8 bears against said washer,

the other end of said spring bearing against the inner end of a wooden tube '11, inclosed within the tube 1. A nut t threaded in the tube I a short distance from its outerend, serves to hold the tube 1', in osition against the tension of the sprin s. I he mouthpiece M is secured in the en of the tube I above the nut 47.

By the construction above described it is apparent that the mouthpiece of the transmitter is readily adjustable with reference to the transmitter and that the tension of the spring 8 produces suflicient frictional engageuser,

ment i the ball-and-so cket joint'of the'tube H and I to hold the mouthpiece in its adjusted position.

Iclaim- 1. The combination with harness for a. head telephoneset, of a receiver and a transmitter mounted on opposite sides of said harness and adapted to fit over the ears of the user, a tubular member having one end secured to the communicating orifice of said transmitter and provided at its other end with a spherical head, a second tubular member provided with a mouthpiece and inclosing said head to form a ball-and-socket joint therewith, whereby said members are adjustscribed.

able, and means for holding said members in their adjusted positions, substantially as de- 2." The combination with harness for a head telephone set, of a receiver'and a transmitter mounted on opposite sides of said harness and adapted to iit over the ears of the atubular member having one end secured to the communicating orifice of said transmitter and provided at its other end with a spherical head, of a second tubular member inclosing said head and forming a ball-and-socket joint tube inclosed in said second tubular member, a nut for holding the wooden tube in position, a coiled spring bearing against said wooden tube and said spherical head, Whereby said ball and socket are held in their adjusted positions, and a mouthpiece carried by said second tubular member, substantially as described.

In witness whereof I hereunto subscribe my name this 8th day of September, A. D. 1905.
